Jeff Hinkley, undercover investigator for the British Horseracing Authority, is looking into the shady activities of a racehorse trainer. Tailing his quarry through the Cheltenham Racing Festival, Jeff unexpectedly is witness to a gruesome murder. Could it be connected to the trainer's recent ban for administering illegal drugs to his horses? Days later, more horses test positive for prohibited stimulants, a scandal that could throw horse-racing into disrepute. To limit the damage to the sport, it's critical that Jeff find the perpetrator . . . but he'll soon learn he's up against someone who will stop at nothing to prevail.
